JOHN D. OBRIEN, OF ST. LOUIS, MISSOURI, ASSIGNOR TO NATIONAL PATENT LATH AND MANUFACTURING COMPANY, A- CORPORA- TION OF MISSOURI.

SHEET-LATHING FOR BUILDINGS.

SPECIFICATION forming part of Letters Patent N0. 773,886, dated November 1, 1904.

Application filed November 4, 1903. Renewed September 12, 1904. Serial No- 224,183. (No model.)

To (LIZ whom it may concern.-

zen of the United States of America, and a resident of the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in SheetLathing for Buildings, of which the following is a specification.

This invention relates to woven sheet-lathing for buildings, and more especially to the type of such lathing which forms the subject-matter of my prior Letters Patent, No. 721,074, of February 17, 1903, and has for its object to provide a simple and efiicient means for the ready repair and strengthening of broken, defective, or weak portions or spots in the woven sheet-lathing, all as will hereinafter more fully appear and be particularly pointed out in the claim. I attain such object by the structural arrangement of parts illustrated in the accompanying drawings, in which' Figure 1 is a perspective view of a portion of woven lathing involving the present improvement; Figs. 2 and 3, detail sections of the same at lines as w and w m, respectively.

Similar numerals of reference indicate like parts in the different views.

As representedin the drawings, the presentsheet-lathing is of the same structural formation as in my former patent, No. 721,074, and comprises a longitudinal series 1 and a transverse series 2 of thin wood strips interwoven together to constitute an extended sheet of lathing for builders use.

In the practical use of such sheet-lathing it has been found that owing to knots and other naturally-occurring imperfections in the wood strips frequent breakage of the strips take place during manufacture and handling. In consequence weak spots are formed at such points of breakage in the sheet-lathing to interfere with the rapidity of the subsequent plastering operation. WVith a view to overcome such defects in an eflicient and economical manner the present improvement consists in the application of a short reinforce-strip 3 over each of such breaks or imperfections and the attachment of such reinforce-strip firmly and securely in place by interweaving the respective ends thereof beneath the adjoining strips of the sheet-lathing which lie in a direction transverse to such reinforce strip or strips in manner clearly indicated in the drawings.

By means of the present improvement all lengths or parts of the wood strips can be utilized in the manufacture of the present form of sheet-lathing with but very little waste and with a corresponding increase in economy of manufacture.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination in sheet-lathing for buildings, of thin flexible strips of wood interwoven together to constitute a plaster-foundation, and one or more short reinforce-strips interwoven in place between adjoining strips of the sheet-lathing which are transverse to such reinforce strip or strips, substantially as set I
